5. In a machine for applying and sealing closures to receptacles, a stationary bed arranged with a raceway, two spaced and alined plungers arranged in alinement above the raceway in the table, a slide reciprocable longitudinally of the raceway, pivoted pawls carried by said slide to engage and advance the receptacle bodies in the raceway during the forward movement of the slide to successively position the bodies below the plungers, said pawls being adapted to pass under the bodies during the return movement of the slide, pivoted spring influenced dogs to have movement laterally into and out of the raceway and normally urged to position in the raceway, said dogs being adapted to be moved out of the raceway by the bodies during the advancing movement thereof and to engage at the rear of the bodies to prevent retrograde movement thereof with the slide, a closure carrying hopper, means reciprooatory in unison with the slide for delivering a closure from the hopper, releasably supporting and conveying the closure to position below the first plunger, means carried by said plunger to release a closure from said closure conveyer and supporting means, apply the closure to the body and partly sealing the same thereto,

and means carried by the second plunger for completing the operation of sealing the closure to the receptacle by an axial movement of the plunger only.

6. In a machine for applying and sealing closures to receptacles, a fixed table, a pair of spaced and alined plungers arranged in spaced relation to the table, closure carrying means, and reciprocatory means for delivering a closure from the closure carrying means and position the same relative to the first plunger and simultaneously position a receptacle below said closure and plunger, said plunger carrying means for applying the closure from said means to the receptacle and partly sealing the closure thereto, and said closure and receptacle delivery means then being operative to position the receptacle with the partially sealed closure to the second plunger, and said latter plunger carrying means for completing the closure sealing operation.

7. A machine for'applying and sealing closures to receptacles as claimed in claim 1,

wherein the closure and receptacle delivery means is operative in unison to deliver a closure and receptacle to the first plunger when a receptacle with the partially sealed closure is delivered from said plunger to the second plunger, and to deliver the com.- pletely sealed receptacle from the second plunger during the successive movement thereof and during said movement advancing a partially sealed receptacle to the second plunger and delivering a closure and receptacle to the first plunger.

In witness whereof I have signed this specification. V
